Technical Field
[0001] This utility model relates to the field of injection molding machine control and detection, and in particular to a signal detection device for injection molding machines that can replace the function of a robotic arm. Background Technology
[0002] Currently, injection molding machines are equipped with various auxiliary machines. Robotic arms, as one type of auxiliary machine, can efficiently handle molded products while ensuring safety. After the injection molding machine is assembled, its built-in robotic arm signal interface needs to be tested to ensure normal communication between the machine and the auxiliary machine, thereby improving product quality.
[0003] However, in practice, using physical robotic arms for inspection not only occupies a large space but also causes difficulties in installation and operation, is not portable, and poses significant safety hazards. Therefore, there is an urgent need for a simple device that can simulate the various functions of a robotic arm for inspection on an injection molding machine. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a signal detection device for injection molding machines that can replace the function of a robotic arm. It enables rapid detection of the robotic arm signal interface and improves the portability and ease of use of the detection device.
[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:
[0006] A signal detection device for an injection molding machine that replaces the function of a robotic arm includes a signal input module, a signal output module, and a communication connector. The signal input module includes several signal input circuits that respond to external triggers to simulate the output of various functional signals from the robotic arm to the injection molding machine. The signal output module includes several signal output circuits that receive the various functional signals output from the injection molding machine to the robotic arm for corresponding indication. Both the signal input circuits and the signal output circuits are coupled to the communication connector. When the communication connector is connected to the robotic arm signal interface on the injection molding machine, the signal input circuits can establish a communication connection with the injection molding machine to send functional signals to the injection molding machine in response to external triggers, and the signal output circuits can establish a communication connection with the injection molding machine to receive the functional signals sent from the injection molding machine to the robotic arm.
[0007] Preferably, the injection molding machine is equipped with a controller, and the robot arm signal interface is coupled to the controller.
[0008] Preferably, the signal input circuit includes an on / off switch. When the communication connector is connected to the robot arm signal interface, one end of the on / off switch can be coupled to the power supply end of the controller to supply power to the signal input circuit, and the other end can be coupled to the signal receiving end of the controller to receive the functional signal output by the signal input circuit.
[0009] Preferably, the signal output circuit includes an indicator. When the communication connector is connected to the robot's signal interface, one end of the indicator can be coupled to the grounding terminal of the controller to ground the indicator, and the other end is coupled to the signal output terminal of the controller to receive the functional signal output by the controller.
[0010] Preferably, the on / off switch is a toggle switch.
[0011] Preferably, the indicator is an LED indicator.
[0012] Preferably, the controller is coupled to a control panel, which is equipped with a trigger unit and a display unit. When the communication connector is connected to the robot arm signal interface, the trigger unit can respond to an external trigger and send a control signal to the controller, so that the controller sends a function signal to the corresponding signal output circuit. The controller can also receive the function signal sent by the signal input circuit to control the display unit to display the corresponding function status.
[0013] Preferably, the connecting lines between several signal input circuits, several signal output circuits and communication connectors are all integrated into a multi-core wire.
[0014] Preferably, both the signal input module and the signal output module are housed within a housing, while the communication connector is located outside the housing. The side wall of the housing has perforations for multi-core wires to pass through.
[0015] This utility model, by adopting the above technical solution, has significant technical effects:
[0016] 1. The signal detection equipment can not only quickly detect the signal interface of the robotic arm, but also is more compact and portable than the robotic arm itself, while being easier to operate and safer.
[0017] 2. It uses a communication connector to connect with the robot's signal interface, which can not only independently complete the detection of all signal points of the robot, but also make it more efficient, stable and safe.
[0018] 3. By using on / off switches and indicators for signal input and output, the operation interface of the testing equipment can be made simpler and more intuitive, further improving operation efficiency and convenience;
[0019] 4. The signal detection equipment can be adapted to various types of robotic arm signal interfaces, making it more versatile and thus expanding its application range. Attached Figure Description

Detailed Implementation
[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 and Figure 2As shown, this embodiment discloses a signal detection device for an injection molding machine that replaces the function of a robotic arm. It includes a signal input module 1, a signal output module 2, and a communication connector 3. The communication connector 3 is preferably a 32-pin quick-connect connector, which effectively improves the connection stability and ease of assembly / disassembly between the communication connector 3 and the robotic arm signal interface 19. The signal input module 1 includes several signal input circuits 5 that respond to external triggers to simulate the output of various functional signals from the robotic arm to the injection molding machine 4. The functional signals output by each group of signal input circuits 5 include, but are not limited to, a mold closing permission signal, a mold area safety signal, a robotic arm emergency stop signal, an ejector permission signal, or an ejector permission signal. The signal output module 2 includes several signal output circuits 6 that receive the functional signals output from the injection molding machine 4 to the robotic arm for corresponding indication. The functional signals output by the injection molding machine 4 include, but are not limited to, an injection molding machine emergency stop signal, a mold opening completion signal, an injection molding machine safety device signal, an ejector pin retraction completion signal, an ejector pin advance completion signal, or a mold closing stop signal. Several signal input circuits 5 and several signal output circuits 6 are coupled to a communication connector 3. When the communication connector 3 is connected to the robot signal interface 19 on the injection molding machine 4, the signal input circuits 5 can establish a communication connection with the injection molding machine 4 to send functional signals to the injection molding machine 4 in response to external triggers, thereby enabling the injection molding machine 4 to provide functional status indications. Similarly, the signal output circuits 6 can establish a communication connection with the injection molding machine 4 to receive functional signals sent from the injection molding machine 4 to the robot, thereby enabling the signal output circuits 6 to provide corresponding functional status indications. Specifically, the injection molding machine 4 is equipped with a controller 7, preferably a PLC, and the robot signal interface 19 is coupled to the controller 7 to achieve a communication connection between the two.
[0025] To enable the input function of the signal input circuit 5, the signal input circuit 5 includes an on / off switch 8, which is a toggle switch. In this embodiment, when the communication connector 3 is connected to the robot arm signal interface 19, one end of the on / off switch 8 can be coupled to the power supply terminal 9 of the controller 7 to supply power to the signal input circuit 5, and the other end is coupled to the signal receiving terminal 10 of the controller 7 to receive the functional signal output by the signal input circuit 5.
[0026] To achieve functional feedback in signal output circuit 6, signal output circuit 6 includes an indicator 11, which is an LED indicator. In this embodiment, when communication connector 3 is connected to robot arm signal interface 19, one end of indicator 11 can be coupled to ground terminal 12 of controller 7 to ground indicator 11, and the other end is coupled to signal output terminal 13 of controller 7 to receive functional signals output by controller 7.
[0027] To facilitate closer and more intuitive communication between the injection molding machine 4 and the robotic arm, an external control panel 14 is coupled to the controller 7. The control panel 14 includes a trigger unit 15 and a display unit 16. The display unit 16 is preferably a touchscreen, and the trigger unit 15 is a touch button integrated into the touchscreen. In this embodiment, when the communication connector 3 is connected to the robotic arm signal interface 19, the trigger unit 15 can respond to an external trigger by sending a control signal to the controller 7. This causes the controller 7 to send a function signal to the corresponding signal output circuit 6. Furthermore, the controller 7 can receive the function signal sent by the signal input circuit 5 to control the display unit 16 to display the corresponding function status.
[0028] To ensure the portability and protection of the signal detection equipment, the connecting lines between several signal input circuits 5, several signal output circuits 6, and the communication connector 3 are all integrated into a multi-core cable 17. The signal input module 1 and signal output module 2 are both housed within a housing 18, while the communication connector 3 is located outside the housing 18. The side wall of the housing 18 has through holes for the multi-core cable 17 to pass through, and the multi-core cable 17 is fixed to the side wall of the housing 18 by a fastening connector 20. An on / off switch 8 and an indicator 11 are both located on the upper surface of the housing 18, allowing testing personnel to operate the detection equipment more conveniently and intuitively.
[0029] The specific usage process is as follows:
[0030] When using the signal detection equipment, first connect the communication connector 3 of the detection equipment to the robot arm signal interface 19 built into the injection molding machine 4 to complete the communication connection between the signal input module 1 and the signal output module 2 and the built-in controller 7 of the injection molding machine 4. Then, sequentially trigger the on / off switches 8 on the housing 18 to allow each signal input circuit 5 to send functional signals to the controller 7 instead of the robot arm. The testing personnel can then observe the on / off status of each functional signal in the display unit 16. If the on / off status of each functional signal is normal, it indicates that the communication between the robot arm and the injection molding machine 4 is normal. Conversely, if the on / off status is abnormal, the robot arm signal interface 19 needs to be reworked.
[0031] Then, the inspector triggers each trigger unit 15 on the control panel 14 to send functional signals to the robotic arm. Each output functional signal enters a signal output circuit 6. If the indicator 11 in each signal output circuit 6 is lit, it indicates that the functional circuit is normal. Conversely, if the indicator 11 in a certain signal output circuit 6 is not lit, it indicates that the communication of that functional circuit is abnormal and rework is required.
[0032] To facilitate the identification of the functions of the on / off switch 8 and the indicator 11 by the testing personnel, corresponding labels (not shown) can be affixed to the surface of the housing 18, thereby improving the ease of use of the signal detection equipment.
